My present invention relates to pew and useful improvements in hosecop lipgs and 2 its principal object aims to rpy1 .device of is character which ma service.

A more specific object of my invention is to provide a hose coupling which consists essentially in two matin coupling elements and a pair of lockin s eeves which are rotatable on the coup ing elements and engageable with each other for draw1ng the meeting faces of the couplin elements into sealing engagement with see other.

The above and other incidental objects of a similar nature which will be hereinafter more specifically treated, are accompllshed by such means as illustrated in the accompanying drawings, described in the follow- 1n specification and then more particularly omted out in the claim which is appended ereto and forms a part of this app ication. With reference to the drawings, wherein there has been illustrated the preferred embodiment of the invention as it is reduced to practice, and throughout the several views in which similar reference numerals designate corresponding arts, Figure 1 is a view in elevation, showing the couplin closed; Fi 2 is a longitudinal section ta en medialFy through the coupling, the nipple being shown in elevation. I ig. 3 is a section on the line 3-3, of Fig. 2' and Fi 4 is a detail perspective view oi one of t e coupling sleeves.

As illustrated in the accompanying drawings, my improved hose coupling includes as its essential elements, a pair of tubular couplin members 10 and 11 and a pair of coacting s eeve members 12 and 18 which are engageable with each other in a manner to be hereinafter more fully described, for either drawing the members 10 and 11 into sealing en agement with each other or .for releasmgt em.

or The members 10 and 11 are substantially similar in construction, each hem from a metal tube, one end of whic is trunformed chea y manufieetured and will he d e e m opted, providing a dia onally extending ed n 14, in each instance. lhese edges 14 of the members 10 and 11,are dc'si nod to engage each Other when t e coupling is From the quter bnd bf one 1 of the membprs 10 and 11,, there extends a nipple, as indicated at 1 5 and 1.6. These members 15 and 16 are of less diameter than the members 10 and 11 and are ,coaxially disposed with respect thereto. nular ribs or corrugaa ne- 17 are forms on the members 15 and 16 'for the obvious purpose of holding the has; he has aiasts cidsate r mo a fine? I ing e ements.

he outer ends of the members 10 and 11 are provided with the segmental grooves 18 and 19. The formation of the grooves 18 and 19 results in the provision of the stop flanges on the sleeves 12 and 13 for limiting the rotation of the sleeves as will be hereinafter more fully described.

The sleeve members 12 and 13 are of such diameter that they snugly engage over the members 10 and 11, as best shown in Fig. 2. Each sleeve is provided with a centrally located enlargement 22 of polygonal form so that a wrench or eguivalent tool may be conveniently erwoye in closing or opening the coupling. e adjacent terminals of the sleeves 12 and 13 are provided with the pairs of lugs 28 and 24 respectively. The lugs 23 of the sleeve 12 are oppositely directed with respect to each other as are the lugs 24 of the sleeve 13. The inner edges of the lugs 23 and 24 are spaced from the adjacent terminal edges of the sleeves a distance substantially canal to the width of each lug. These inner e ges of the lugs are also inclined in such manner that when the mating lugs 23 and 2 1 of the two sleeves are moved 0 )positely with respect to each other, the sieeves will be drawn toward each other with a resultant urging of the edges 13 and 14 of the members 11 into sealing engagement with each other.

It is now to be noted that a segmental flange 25 extends inwardly 'from the outer terminal of each of the members 12 and 123 and that these segmental flanges are engageab le against the outer terminals of the couplmg elements 10 and 11. The engagement of the members 25 with the members 10 and 11 prevents the longitudinal movement 0 I the sleeves overthe members 10 and 11 in one direction. The members 25 are of such length that the lugs 20 and 21 may bemoved u suiiicient distance to permit the disengag mg of the lugs 23 and 24 when it is desired to disconnect the coupling. The lugs 20 and 21 serve by engagementwith the terminals of the stop flanges 25, to normall hold the edges 14 and the members 10 an 11 in approximate mating relation.

In reduction to ractice, it has been found that the form of t is invention illustrated in the drawings, and referred to in the above description as the preferred embodiment, is the most efiicient and practical; that the conditions concurrent with the adoption of this device will necessaril vary, it is desirable to emphasize the fact t at various minor changes in details of construc- Zion, proportion and arrangement of parts be resorted to, when required, without sacrificing coupling members, a pair yet realizing oi this patent may be obtained for five cents each, by addressing the any-of the advantages of this invention, as defined in the appended claim.

What is claimed is A coupling including a pair of mating of sleeves rotatable thereon for closing or releasing the coupling members, a segmental shoulder formed on. the outer terminal of each of the coupling members, and an flange formed on the outer terminal of each sleeve, said shoulders being engageable with. the terminals of the flanges for limiting the flotation of the sleeves on the coupling memers.

In testimony whereof I hereunto atiix signature in the presence of two Witnesses.
